Characteristics of Polyester Foam

Polyester foam, also known as Ester, is a flexible, open-cell type of polyurethane foam that has a near-infinite amount of applications due to the following characteristics:

  • Compress-ability
  • Cushioning
  • Energy absorption
  • Fabrication-ability
  • Flexibility
  • Insulating
  • Light-weight
  • Low thermal conductivity
  • Low water vapor transmission
  • Mildew-resistance
  • Resiliency
  • Sound absorption
  • Vibration dampening

Polyester Foam

In addition to fabricating polyester foam products to custom designed specifications, New England Foam stocks polyester foam in bun, forms, in densities ranging from 2 to 4 pounds per cubic foot (PCF) and those colors most requested: charcoal (black) and blue. Additional densities and custom colors are available upon request.

Anti-static, conductive electrostatic dissipation (ESD) FR, UL94HF1 types of polyester foam are also available upon request.


The Cell Structure of Polyester Foam

Polyester foam’s most brilliant attribute is its evenly spaced cell structure with a high proportion of closed cells or “windows” that reflect light.

This large amount of windows makes polyester foam ideal for sealing as it naturally prohibits the flow of air.

The uniform cell structure inherent in polyester foam is perfectly suited for the reticulation process (the manufacture of filter foam).

New England Foam stocks polyester filter foam ranging from 10 PPI (PPI = pores per inch) to 100 PPI.


Polyester Foam vs. Polyether Foam

Traditionally, polyester foam has a higher “tensile” strength than its polyurethane foam counterpart, polyether foam.

Polyester foam is also more resistant to hydrocarbons and alcohols than polyether foam.

In applications where the polyurethane foam will come into contact with gases, such as oxygen, nitrogen and/or carbon dioxide, the polyurethane foam should be manufactured with polyester-based polyols.

In applications where the polyurethane foam will come into contact with a liquid-based solution, the polyurethane foam should be manufactured with polyether-based polyols.


Manufacturing Polyester Foam

More costly and difficult to manufacture than polyether foam, polyester foam is manufactured in a variety of premium product grades, each with the characteristics to satisfy the demands of every project where presentation is crucial.

Due to a higher viscosity rate, polyester foam exhibits physical properties not obtainable with other types of polyurethane foam; including superior solvency, abrasion and cut-resistance.

It is during manufacture that flame retardant additives can be introduced to meet various fire code standards, as well as anti-microbial, anti-static, conductive and/or electrostatic dissipate (ESD) additives.
